Anybody have recommendations for sealing up the venting on a RV or Travel Trailer.

I'm concerned about the breathing and exhaust vents on my refrigerator getting to much dust in them to breath. I was thinking something like a breathable barrier like Tyvek, something with a very fine weave but that still breaths? How about the water heater as well, cover it when its not on and uncover when your running it (it puts of a ton of heat)??

If it's fine enough to keep dust out, it's probably going to inhibit circulation enough to create problems. We run the water heater in the morning and it keeps temps warm throughout the day. The only thing I do is cover the range vent on the outside- My first year (with it uncovered), I ended up with dust dunes on the cooktop.

Savannah: I don't know what it is, but no thread here escapes alive. You'll get 1 or 2 real answers at minimum, occasionally 10 or 12, and then we flog it until it's unrecognizable and you can't get your deposit back.

We have an older rv and I taped up the heater grate with cardboard and all of it's vents with blue painters tape. Anything you can see daylight from outside into the coach though a access door is a place for tape I used a whole roll !
